During the third quarter of the Magic’s blowout loss to the Clippers Monday night, Nikola Vucevic went up to try and block a Blake Griffin shot, ended up getting flipped and took a hard fall where he landed on his side and his head hit the floor.

Vucevic suffered a concussion and the Orlando big man is likely out at least a week, tweets John Denton of the Magic’s official Web site. Vucevic is now in the league’s concussion protocol, where he will have to pass a series of mental tests (based on a baseline from an earlier test he took) to show he is symptom free plus do that after undergoing a series of increasingly physically demanding tests.

Vucevic is averaging 13 points and 11 rebounds a game for the Magic, playing well on a struggling team and looking like one of the guys they could count on as a long-term part of the core being built there.
